Thanks for your response bill. No I doubt they saved any of the oil. It is going into a different dealer on Monday

Now the problem is that any evidence of the true underlying problem may have been cleared out of the computer when they reset all the codes and dumped away when they changed the oil. Just going to make it harder for the mechanic to figure out and possibly in the shop longer

Frustrating for sure

I agree with you that it is going to be harder to diagnose. Still, my concern is that there may be other internal issues. Check that oil if you get a chance. If there's enough garbage to cause the DTC, it's possible you will be able to see or feel it in the oil.

Also, I don't mean to sound negative towards your engine's prospects, but I am the kind of person who looks at the worst possible scenario and then goes back from there. It could be something stupidly simple and in the hands of a competent technician it would be resolved quickly.

Keep us posted.

Well now i have a check engine light also...

[Power Hungry]

DTCs?? Are they the same ones as before?

[Caforddude]

Yep the same codes.

I checked the dipstick like you said and there is no metal flakes in it NOR any grittiness.

Couple people I have talked to think that because there was a TSB on aftermarket oil filters that they claimed grittiness, did the oil change and called it a day simply clearing the codes without doing any ACTUAL diagnosis as to the real problem.

I do find it ironic, funny, something that the tech would say the oil was brown and gritty yet that didn't show up on ANY paperwork.

I would think that would certainly be note worthy if it had in fact happened. Leads me to believe more and more that the "brown gritty oil" statement made to me by the service writer was A) fabricated by him for an unknown reason or B) fabricated by the mechanic for whatever reason.

Noteworthy for no other reason the to work to deny a warranty claim..I'm sure the oil was instantly discarded in their oil tank and could in no way EVER be recovered to see it for our own eyes.

Welp the truck went into a NEW dealership today. Has been my second choice behind DREW for some time laziness prevented me fromtaking it there in the first place.

Service adviser called me at noon today saying she and the service manager had taken it for a test drive to see if the problem could be duplicated and her response was "OH MY GOD I DIDN"T KNOW IF WE WOULD MAKE IT BACK TO THE DEALERSHIP"

They did some sort of "pinpoint" test she called it and determined there were no electrical issues. First thing in the morning they are going to pull the valve covers off and check a solenoid? to see if it is working. If that is the problem then a replacement and I'll be good to go. If not then appaerntly they tear the engine down enough to pull the cam phasers and cams?

Either way my truck has been there since about 10am and I have gotten 3 calls. One to let me know it got there ok, 1 to let me know the results of the test drive and 1 a few ago to let me know they finished the electrical testing and would be pulling the valves tomorrow. Total time on the phone with the service writer....About 3 minutes. Is that too much to ask?

Glad to see Customer service IS still alive.

I'll keep ya posted.
